Not the most impressive thing in the world, but I made a universal brick shader for the houses in my castle, going for an industrialized Brick Gothic style. here's the network Also my trimsheet! Aw yeah...
Well I was going for groutless bricks, like this: http://www.cgtextures.com/texview.php?id=38973&PHPSESSID=ipee4ed7m59sp0acvh7n4d3ob0 And here's the concept (red bricks under the plaster) Now that you mention it though, I might go back and redo them. Does look kinda silly without grout :P
